Maxime Lasseron, a research doctorate in the National Museum of Natural History of Paris, inspects the femur of an enormous dinosaur, which could have measured 100ft long in life, on July 24, 2019. /VCG Photo

The huge thigh-bone was discovered earlier in the week during excavations at the palaeontological site of Angeac-Charente, near Châteauneuf-sur- Charente, south western France. The bone is an exceptional state of conservation. / VCG Photo

The 140 million-years-old, two meters long, 500 kilogram femur belonged to a Jurassic period Sauropod, the largest herbivorous dinosaur known to date. / VCG Photo

While its skeleton is nowhere near complete, other bones from the animal's pelvis were also excavated. / VCG photo
